Thanks skinny, helpful info as always.
I took a trip two weekends ago where I had the Path loaded up. We went on a camping trip to Lake Roosevelt. We were towing the boat, had all of the camping gear in back, and bikes on the roof (see crappy pic below

). I'd say we were near the GCVWR. Overall the Path did great. The driving / handling dynamics were good. Braking was also good. The trailer has brakes on both axles so it doesn't feel like it's relying on the vehicle much. The drive up to the lake was overcast with light rain. We climbed grades up to 7% with no problem (gas mileage obviously goes way down).
We drove home on Saturday afternoon and it was a hot sunny day, probably around 106 - 110 degrees F. On one section of road we were climbing a 7% grade for maybe 2-3 miles. The A/C was on of course because it was hot outside. I was keeping a close eye on the engine temp gauge. Maybe a mile and half into the climb I noticed the engine temp start to creep up. The engine RPM automatically dropped down from ~5K to ~3.5K and our speed decreased to about 45 MPH. I pressed the gas pedal a bit to try an maintain 60 MPH, but there was no response. As I watched the engine temp gauge drop back to it's normal level I realized the computer must have taken over to avoid unsafe engine temps. In hind sight, it seems like the system worked as you would expect it to. We still continued to climb the hill, just at a slower speed.
At the next climb we came to I tried to keep the RPM < 5K to keep heat down. I had a little trouble holding the gear I wanted. Maybe next time I should go to manual mode to keep the tranny in the gear I want.
